Can't export to XLSX

When I try to export any report to XLSX I get the following message in the browser:

This site can’t be reached The web page at might be temporarily down or it may have moved permanently to a new web address.

Anything I’m missing?

Which version are you using?


Not sure, seems to be working for me.

Which version of PHP?

PHP Version 7.0.33-0+deb9u1

I’d suggest creating an issue GitHub, it’d be helpful to know if other people are seeing the problem.
